It actually was bothering me since I saw it first... In the scene where Junpei caries Miho to his room. Or on the following panels.

It's in every ninja room they are passing.

It is also in Junpei's room.

A TV. A CRT TV. WITH NO CASE.

An open frame, chassis only, TV or maybe a VGA monitor #remember2001 (also I had a few SVGA CRT monitors, I remember them and I remember analog TV. I know people who still use a 14 in NEC TV they bought in 1990, today)

Yeah ?

But why?

Why put a device with high voltage parts exposed, into the room whose walls/panels are made of paper? Not to mention that parts of the tube at the back can be pretty hot? Or that it is an implosion hazard if something falls on it? It's a cool detail but is there an explanation? Does it come from some ninja stories genre ?

I think part of the explanation is that Jumpei doesn't live in this room anymore. He has his apartment next door to Tsubasa's old place [70]. This room is where he grew up, and that was his tv from years ago when he was a teenager. Either Junpei Mom keeps things like he left them in the hopes that he'll visit more often, or maybe there are enough spare rooms at Ninja compound that they haven't needed to give it to someone else yet.

Also, I think part of the ninja ethic would be that they were always careful and ware of their surroundings. Having hazardous stuff around shouldn't be a problem, and might be seen as valuable.

Cool thought... however CRT TV's opened up like that tend to attract a lot more dust (when closed in a case they do too, but you can't see it until you open it)... so it's not just high-voltage fragile implosion hazard, but also a dust ball and ozone-generator... iow not very good for your health even if one is a ninja ...
